LEAD-HOLDER.

Specification of Letters Patent.

Patented July 24, 1917.

Application filed May 7, 1917. Serial No. 166,904.

To all whom it may concern:

Be it known that I, WILLIAM K. HOLMES, a citizen of the United States,and a resident of the city of New York, borough of Brooklyn, in thecounty of Kings and State of New York, have invented a new and ImprovedLead-Holder, of which the following is a' full, clear, and exactdescription.

My invention relates to lead holders, and has reference moreparticularly to means for engaging the lead in the holder to prevent theaccidental displacement of same.

An object of the invention is to provide a' simple and inexpensivearrangement which will have a frictional engagement with the lead in theholder and prevent the lead from dropping out of the holder.

I attain the above and other objects of my invention by the structureconventionally disclosed in the accompanying drawings, wherein similarcharacters of reference indicate corresponding parts in both views.

Figure 1 is a longitudinal fragmentary section through a lead holderembodying my invention; and

Fig. 2 is a fragmentary perspective view of the lead holder with themeans for frictionally engaging the lead in the holder and preventing anaccidental displacement of same.

Before proceeding to a more detailed description of my invention it mustbe clearly understood that my frictional grip has application moreparticularly to pencils in which the lead is backed by a feed wire andnot gripped by a clutch.

Referring to the drawings, 3 is the tube which carries the lead. It hasan extension 4 forming a guide for a block 5 in which a bar 6 isanchored. One end of the bar en- 7 abuts when the pencil is used. Theother end of the bar 6 projects through a slot 8 in the guide 4; toengage a spiral 9 which is revoluble through the medium of a head 10bearing in the end of a shell 11. Said shell 11 also incloses the tube 3to which it is secured so as to prevent the rotation of said tube 3.

To prevent the dropping of the lead 7 in the tube 3 I provide a notch 12near the end of the tube 3 where the' lead projects. Through this notchthe surface of thelead may be frictionally engaged by a split yieldingsleeve 13 which has a projection 14 en tering the notch to engage thelead 7. The engagement of the depression 14 with the lead prevents anaccidental displacement of the lead, but it does not interfere with themovement of the lead under the action of the bar 6. The provision of thesplit sleeve in no way interferes with the action of the pencil, andbeing inclosed within the shell 11 I it cannot be tampered with. Thedepression on the split sleeve within the notch 12 locks the sleeve tothe tube 3 and, therefore, prevents an accidental displacement of thesplit sleeve on the tube, thus the depression 14 serves two purposes,-tofrictionally engage the lead within the tube and to lock the sleeve onto the tube.

I claim:

In a lead holder of the class described, a

tube for carrying a lead, means for moving the lead out of the tube,said tube having a V-notch disposed transversely of the tube near theend where the lead is adapted to project out of the tube, and an opensleeve on the tube having a V projection entering the V notch forengaging frictionally a lead located in the tube, whereby the lead inthe tube is prevented from falling out.

WILLIAM K. HOLMES.
